The Other-Ventures were marketed by Adventure International as a series of
games by authors other than Scott Adams. Death Planet: The Dog Star
Adventure by Lance Micklus is #5 in this set. This is an obscure one,
compared to the rest of the Other-Venture series. For one, it's only
identified as an Other-Venture on the back of the package (the others have
the OV logo and a number on the front cover).

Dog Star was originally published in the May 1979 issue of
Softside, a TRS-80 magazine, as source code that ambitious
readers could type in themselves (and modify to create their own
adventures, it turned out). It was the first adventure game to be
published this way.

Lance Micklus wrote a number of non-adventure games that Adventure
International published, including a checkers program and several arcade
games. Apparently AI also decided to re-release Dog Star Adventure
as part of the Other-Ventures series. The "Death Planet" title heading
is AI's addition. I doubt this was released for any system beyond the
TRS-80. Also not sure whether it uses the same game file format as the
other Other-Ventures (which themselves are in a different format than
the Scott Adams Adventures). It could simply kick off the TRS-80 BASIC
interpreter.
